"My pledge is to put cutting the cost of living and cutting carbon emissions at the heart of all my policies. My London campaign shows that, done right, fighting climate change saves, not costs, money. Being Green is about believing in a fair share for everybody."

"London has lost record numbers of street trees. Our city has the worst record on recycling in the country. And, despite being one of the first major cities in the world to introduce clean air regulations, thousands of Londoners die every year from illnesses relating to poor air quality."

"Over the last eight years, London has become a world leader in the battle to prevent catastrophic climate change. Since I became mayor, there has been an 83% increase in cycling, and London is the only major city in the world to shift from private car use to public transport."

"We will plant 10,000 new trees to help ensure that London becomes the greenest capital in Europe. All major new developments must be self-sustaining in energy, waste, and water consumption. Our key theme will be improving the quality of life for all Londoners."
